What rare earth metals are found in group?
They are called the Lanthanides Lanthanum Cerium Praesodymium Neodymium Promethium Samarium Europium Gadolinium Terbium Dysprosium Holmium Erbium Thulium Ytterbium Lutetium See the exterrnal link
What is the only synthetic element in the lanthanide series?
Promethium (Pm) is the only synthetic element in the lanthanide series. It is not found naturally on Earth and is typically produced in nuclear reactors.
Does cerium need to be refined if it is found in nature or is it made in the laboratory?
Cerium is found as a compound of many other rare earth metals, so it is processed using several acids and techniques that rely on the properties of the other metals and their compounds to remove them.
What is the elementt Eu on the periodic table?
Eu is the chemical symbol for Europium. Europium is a rare earth element that is commonly used in the production of phosphors for electronic displays, such as those found in TVs and computer monitors.
Which element has a mass 100 less than cerium?
Isotopes of curium have masses between 232 and 252. It is your choice to subtract 1oo from (232 to 252) and to found an isotope. I have the same homework!!! The answer is calcium. - Linz The most important isotope of curium has an atomic weight of 247; 247-100 is 147. This is the mass of an important isotope of promethium.
What are cerium and europium examples of?
Cerium and europium are examples of rare earth elements, a group of metals that are crucial for various technological applications such as electronics, magnets, and lighting. Europium is specifically known for its ability to emit red light, making it important for producing vivid colors in some types of lighting and displays.

Who found cerium?
Wilhelm Hisinger founded the elment cerium.
To which period and family does promethium belong?
Promethium belongs in the 7th family. The 7th family is The Lanthanide family.

Is cerium man made?
Yes. Cerium is the element they use to make silver, and flint in cigarettes or gas lighters.
What are facts about europium?
Europium is not found in nature as a free element. Many minerals contain europium, with the most important sources being bastnäsite and monazite. Depletion or enrichment of europium in minerals relative to other rare earth elements is known as the europium anomaly. Europium has also been identified in the spectra of the sun and certain stars. Europium has no known biological role. Divalent europium in small amounts is the activator of the bright blue fluorescence of some samples of the mineral fluorite (CaF2). The most outstanding examples of this originated aroundWeardale, and adjacent parts of northern England, and indeed it was this fluorite that gave its name to the phenomenon of fluorescence, although it was not until much later that europium was discovered or determined to be the cause.

What is the valency of promethium?
Promethium is an element and does not have a charge. As it has only be found in trace quantities, its chemistry has not been fully investigated. It has been anticipated that the likely charge when it forms compounds would be +3.
Is promethium malleable?
Yes. Promethium is a rare earth metal and is found in the periodic table in the Lanthanide section. Its symbol is Pm and it has the atomic number 61. It was predicted to exist, but could not be found in the earth's crust. Promethium has no stable isotopes, and what ones it has are relatively short-lived. It was first isolated from spent nuclear fuel, and later discovered in ores of uranium, but only in the most minute quantities.
